EXTENSIBLE GAS-FIXTURE.

To all whom it may concern:

Be it known that I, Louis R. YANSKY,L

citizen of the United States, residing at No. 4

De Kalb street, in the city of Chicago, county of Cook, and State of Illinois, have invented a new and useful Improvement in Extensible Gas-Fixtures, of which the following is a specification.

My invention relates to that class of gas fixtures which are used in dwellings and which are designed for lighting purposes, and which, being adapted to be supported in ceiling of room, can be raised, lowered and adj usted at pleasure at any vertical position between the floor and ceiling of the room.

The object of my invention is to rovide a combined extensible gas light an heating fixture, which can be adjusted close to the ceiling when not in use, and which may be drawn down and adjusted near the floor when used especially for heating purposes, or be adjusted at any intermediate point between these extreme positions. The manner in which I accomplish this object is described in the following specifications and illustrated in the accompanying drawings in which:

Figure 1 is a front elevation of my extensible combined gas light and gas heating fixture adjusted as to height, for ordinary light-- ing purposes. Fig. 2 is a side elevation, the relative positions of the parts being the same as in Fig. 1. Fig. 3 is a central sectional view of one of the gas joints. Fig. 4 is a cross section on the line 4-4 Fig. 3. Fig. 5 is a cross Fig. 6 is a cross section on the line 66 Fig. 3. Fig. 7 is a longitudinal sectional view of the adjustable shade holder bracket, disconnected from the fixture.

In the drawings A is a wood screw provided with a ceiling late A. This screw is adapted to be affixec in a ceiling joist and to thereby support the gas fixture. Aflixed on the head A of this screw is a coiled s ring B. Permanently affixed in the other cm of this spring is a con ling O. The end of the head A and the en of the coupling 0 are spaced from each other in said spring to allow a considerable lateral movement of the fixture and to thereby prevent the breakage of the fixture by lateral pressure applied thereto by 1 using or otherwise.

In one side of the coupling C a supply pi e C is affixed, this pipe being adapter for t e attachment thereto of a flexible tube C the other end of which is attached to the burner Specification of Letters Patent.

of any ordinary permanent gas fixture in the room. The supply of gas passes through the pipe C and gas way in the coupling G into the joint D of which the coupling C forms the middle part D. In the fixture as shown there are seven of these joints. Each of these joints is constructed of the following parts: the central part D two end parts D and D, a connecting pivotal rod D, washers D lock nuts D and end caps D.

The parts D D, and D are cylinders through which the rod D extends. The in terior diameters of these cylinders are adapted to ermit the free flow of gas around the rod, am the exterior diameters are sufficient to allow of sufiicient material to support the connecting parts of the fixture. The center part D may either form an integral part of the cou ling C, or be constructed with a threader aperture D shown by the dotted circle in Fig. 3 and in section in the ends D and D Fig. 3. Each of these ends has an external threaded part D, adapted to support a cap D these caps being adapted to cover the ends of the rod D, lock nuts D, and washers D and together with the washers and nuts to form gas tight ends to the joint D. These several joints are connected together with gas tubes E which form a quadruple toggle joint through which the gas flows, and by which the fixture may be adjusted near the ceiling and be drawn down till the tubes E are in a vertical position, the length of these tubes limiting the distance the burner can be lowered from the highest point at which it is adjusted when the fixture is closed against the ceiling. The friction between the several parts of the joint D is adjusted by the lock nuts and washers on the rod D and the lower part of the fixture is thereby sustained at any desired point. Supported in the central part of the lowest joint D is a pendent gas pi e F, on which a handle F is affixed below t is handle on the pipe F is an adjustable sleeve G, adapted to support an adjustable arm G this arm is formed of two strips of metal, arranged parallel to each other and connected by bolts and thumb screws G One of these bolts and screws passes through the lips of the sleeve G and closes the sleeve on the pipe F; the other bolt and screw passes through a bracket H which is thereby attached to and adjustably supported in said arm G Affixed to this bracket is a shade I. Connected to the pendent pipe F by an elbow J is a horizontal pipe-K adapted to support a gas burner L.

What I claim as new and desire to secure by Letters Patent, is:

1. In a gas fixture of the kind described, the combination of the following parts constructed and connected as describedto Wita coiled s ring; means for securing said spring pendent y to a ceiling; a coupling affixed to the free end of said spring; a series of rotatable joints, each of said joints being composed of three cylindrical members, a threaded center pin extending through said imembers, Washers and lock nuts secured on said pin adapted to hold said members together, said coupling constituting the central member of one of said joints; a pair of caps secured on the ends of each of said joints; a series of tubes afiixed to and connecting said joints as described and illustrated; an L shaped tube affixed to the center member of one of said joints and a burner attached to the end of said tube, said coupling, oints and tubes forming an extensib e gas Way; a bracket supported on said L shaped tube; means for adjustably attaching said bracket to said tube; and a shade attached to said bracket.

2. In a gas fixture of the kind described,

the combination of a coiled spring and means for securing said spring pendently to a ceiling, with a coupling, a series of oints each bein composed of three members rotatably' secure on an axial rod extending through said mem bers, an axial rod extending through said members, washers and nuts secured on said rods adapted tohold said members together, caps on the ends of said joints, aseries of tubes secured to and connecting said joints, a pendent tube affixed to one of said joints, a burner secured on said tubea bracket supported on said pendent tube and a shade supported on said bracket.

3. In agas fixture of the kind described, the combination consisting of a coiled spring adapted to be pendently attached to a ceiling; a coupling affixed to said spring; a series of joints, said coupling forming the center member of one of said joints; a series of tubes afiixed to and connecting said joints; a'tube affixed to the center member of one of said joints; a burner attached to said tube and a bracket and shade supported on said tube as l described.
